UPDATE: Got the files I was looking for, which brings me to my final question regarding sandbox...

Where do I need to place the sandbox gamemode (edited version) in order for it to work on my server? How should I go about including it in my gamemode so it uses the edited version instead of using the default version? What function? Can someone give me an example please?
